1 Claim.

This application is a division of my co-pending application entitled Electric table stove, filed March 28, 1933, bearing Serial No. 663,126.

The invention relates to cooking stoves of the character utilizing electric current as a medium for heat generation.

It is the principal object of the present invention generally to improve the oven construction of portable cooking stoves which are of such dimensions and. weight that they may be positioned for use on a table or like support.

One form that the invention may assume is exemplified in the following description and illustrated by way of example in the accompanying drawings, in which- Fig. 1 is a view in side elevation of the stove, with parts thereof broken away to disclose more clearly the subject matter of the application;

Fig. 2 is an end View of the stove with parts broken away to disclose more clearly certain features of construction; I

Fig. 3 is a view in plan section through the oven of the stove;

- Figs. 4 and 5 are fragmentary views in sec.- tion showing the tray ejector member;

Fig. 6 is a fragmentary View in section through one of the tray guide rails disclosing the manner in which the ejector rod bearing is connected therewith;

30 Fig. '7 is a fragmentary view showing a portion of the interior of the oven and disclosing the guide rail and ejector mechanism; and

Fig. 8 is a fragmentary view in plan section showing the manner in which the forward end of the guide rails are secured to the front wall of the oven.

Referring more particularly to the accompanying drawings, I have illustrated a portable cookstove which is light in weight and of such dimensions that it may be conveniently arranged on a table or like support for use.

The portable cooking stove includes an oven l0 which is formed of side walls II, a rear wall l2, and a front wall l4. These walls are preferably formed of sheet steel by die-stamping. The side and end walls are rigidly connected ,at their junction in any preferred manner. To form the bottom of the oven I provide a horizontally disposed bottom plate l5, which is likewise formed of sheet steel of suitable gauge. This bottom plate is connected to the side and end plates at its marginal edge in any preferred manner. When the side and end walls are assembled with the bottom plate, both the inner and outer side surfaces of the oven are porcelaincoated, either by brushing or spraying, and which, when baked, provides a seal at all of the junctions between the various parts and not only gives the oven a pleasing appearance but enables it to be easily cleansed.

Overlying the oven and forming a top therefor is what I prefer to term a skillet l6, which is formed of a suitable alloy. At one end, this skillet is formed with a spout I! which projects beyond the rear wall l2 of the oven. This spout is fitted with a valve member l8 which may be operated to enable the liquid in the skillet to be discharged through the spout H. To receive liquids from the spout, I have provided a removable container l9, which is removably suspended on the rear wall l2 of the oven beneath the spout. I intend that this container l9 be given a porcelain finish harmonizing with the porcelain finish of the exterior of the oven.

As will be noticed from Figs. 1 and 2 of the drawings, the oven is fitted with four supporting legs 2|], which are connected to the bottom of the -oven and which may be provided with heat-insulating buttons.

The skillet I6 is provided with a removable cover 2|, preferably drawn from a single sheet of material and given a porcelain finish agreeing with that given the exterior surface of the oven.

The valve l8, the container I9, and the cove 2| are all fitted with heat-insulating handles, as illustrated.

The front wall 14 of the oven is formed with an opening 22, to which a hinged door 23 is fitted. The opening 22 is rectangular 'in form and around its perimeter it is formed with a door frame 24, which is drawn from the sheet of material forming the front wall M of the oven. The door frame 24 is so formed that when the door is fitted thereto, the latter will lie at. an acute angle to the vertical; that is to say, the lower edge of the door will be spaced further from the plane of the plate [4 than the upper edge of the door.

The door 23 is formed of a sheet of material and dished at its center portion, which snugly fits within the inner periphery of the door frame 24. The marginal edges of the door surrounding the dished portion thereof are adapted to abut the front surfaces of the door frame. At its lower edge the door is hinged to the door frame by an articulate connection, such as illustrated. This connection may be of any preferred type, or may be of the construction illustrated and described in my copending application entitled V June 7, 1933.

a marginal edges of the dished. portion of the door.

This panel is preferably given a porcelain finish harmonizing with the skillet cover and the exterior surface of the oven. A handle 26 is rigidly secured to the oven door adjacent its upper edge and centrally between the ends thereof, and projects outwardly to provide a means by which the oven door may be manipulated.

Arranged interiorly of the oven are electric heating elements 21, which are electrically connected to a socket 28 at the rear end of the oven, and to which current may be led as in standard practice. These electrical heating elements supply heat'to the oven and for the skilletQand it may be. stated that I may use any preferred type of electric heating elements for this purpose.

Arranged horizontally within the'oven and extending longitudinally thereof .is a pair of guide rails 29, which are channeled in cross-section and preferably formed by die-stamping. These rails are secured at their rearmost ends to the back wall of the oven, either by riveting or otherwise, and are secured at their forward ends to the door frame, as most clearly illustrated in Figs. 3 and 8. g Reference being had .tothesefigures, it will be seen thatthe forward end of each guide rail is formed'with an offset tang between whichand the outer surface of the guide ,rail the inner portion of the door frame is received and clamped. This forms an inexpensive. and a very .secure fastening for theforward end ofthe guide rails. It will be noticed that the bottom surfaces of the guide rails are in substantial alignment with the bottom edge of the door opening 22. The foremost ends of the guide railsproject into the door opening as described, and in alignment with these guide rails the opposite sides, of the door frame are recessed'to receive them. That is to say, the lateral dimension between the inner side surface of the guide rails exceeds the lateral dimension sides of the opening.

' a The rails are, of course, arranged in parallelism so-as to form a guiding and supporting means for a removable oven pan or tray 3|, ,whichisav shallow trayelike structure'having lip-turned sides the guide rails, so that the only place the pan or tray can be inserted into the oven is in alignment with the guide rails. Theseyas previously mentioned, are disposed at the bottom of the oven door opening 22. This prevents any chance of contact between the'pan and the heating elements because, after the tray is inserted into the guide rails, the channeled cross-sectional shape of the latter maintains the pan or tray in a perfect horizontal position, both during insertion and withdrawal 7 thereof.

In order that the tray or pan 3| may be placed in the oven or withdrawn therefrom without grasping it, I have provided what I prefer to The transverse di-.

term an ejector mechanism. This mechanism includes an ejector rod 32 which extends longitudinally of the oven beneath one of the guide rails. The forward end of this ejector rod projects through an opening in the door frame 24 and exteriorly of the door frame it is bent first laterally and then vertically, the vertical portion being fitted with a heat-insulated handle 33. The ejector rod 32 extends parallel to the guide rail and i received in a bearing 34 for reception longitudinally of the oven. This bearing'is provided with an asbestos liner so that regardless, of the temperature within the oven, the sliding movement of the ejector rod in the bearing 34 will be noiseless. This bearing is secured to the guide rail as illustrated in Figs. 6 and '7.

Reference being had to. these figures, it will be seen that the outer surface of the guide rail is slitted and then slightly offset so as to receive a Vertical tang or tab 35 in the bearing 34, By compressing the offset portion toward theguide rail, this tang will be'firmly clamped intoposition. At its innermost end, which is adjacent the rearmost end of the oven, the ejector rod 32 is provided with an ejector member 36, which is a flat member arranged transversely of the oven in a position to engage the rearmost end of ,a tray arranged between the guide rails, Rigidly secured to this fiat member is a bail-shaped member 31 which is disposed intermediate the guide rail and the interior surface of the adjacent side of the oven. The ends of this member 31 engage the interior sides of the oven so as to maintain the flat member 36 in proper position.

The ejector member 32 is connected to the members 36, and 3'! by a ferrule 38 formed as. a part of the members 36 and 31. The member 32 fits loosely within. the ferrule and an ear 38a. on said member extends through a slot 38b in the ferrule (see Figs. 5 and 7) The ear and slot are proportioned to permit rotation: of the member 32 about 90 relative to the ferrule and prevent longitudinal movement of the member 32 relative to the ferrule. It is obvious'that when a tray is in position between the guide rails and the handle 33 is grasped and the ejector rod withdrawn from the oven, the ejector member 36 will engage the rearmost end of the tray and eject the same from the oven, with the handle 33, of course, in advance of the tray. When desiring to replace the tray into the oven, thehandle 33 is swung to the left so that it will engage the outer end of the tray; This turning movement, of course, is permitted by the limited amountof turning permitted the ejector rod 32 relative to the channel 38. In this position the handle will engage the outermost end of the tray and by moving the ejector rod longitudinally andinwardly of the oven, the tray will be replaced. This enables the tray both to be withdrawn from and to be replaced in the oven without the necessity of grasping it. Naturally this is somewhat. of an advantage, particularly when the tray is heated.

In operation the electric stove is constructed and assembled as illustrated and described and may be placed on a convenient support such as a table for use. As the stove is of small exterior dimensions and very light, it is portable in nature and may be moved from place to place.

When the circuit of the heating elements is closed, the oven and skillet will rapidly become sufficiently heated for cooking purposes. The ordinary baking, broiling and toasting operations may be carried on within the oven and the progress of the cooking therein observed through the transparent panels in the oven sides. To extract the pan or tray on which the food is disposed within the oven, it is only necessary to open the oven door and extract the tray by manipulating the ejector rod 32 by means of the handle 33. The latter, as will be noticed, is positioned conveniently at the side of the oven door. To replace the tray, the handle 33 is turned to engage the outermost end of the tray and pushed inwardly to replace the tray in the oven. If desired, food may be fried or stewed in the skillet during the period the oven is in use, or otherwise. If it is desired to remove accumulated liquids in the skillet, this may be done by draining the same through the spout H, the liquids being discharged into the container 19.

I have found in actual practice that an entire meal may be fully and expeditiously prepared economically by means of the stove as disclosed, and that said stove is an extremely useful device and adapted to a great variety of cooking and baking. Further, that the stove is pleasing in appearance and can be manufactured very inexpensively.

While I have shown the preferred form of my invention, it is to be understood that various changes may be made in its construction by those skilled in the art without departing from the invention as defined by the appended claim.

Having described my invention, what I claim and desire to secure by Letters Patent is In combination with an oven having a door opening and a tray slidable through said opening, means for sliding the tray outwardly comprising a rod disposed parallel to the tray in the oven and mounted for sliding and turning movement and having an end extending through the oven wall provided with a handle, and means engageable with the tray to withdraw it from the oven, a ferrule connected with said withdrawing means and mounted on said rod, there being a connection between said rod and ferrule to permit rotation to prevent longitudinal movement of said rod with respect to said ferrule, said handle being positioned to engage the forward end of the tray upon turning movement of the rod to push the tray into the oven.
